REVOLVING FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 254,798, dated March 14, 1882.

Application led December 30, 1831. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. CILLEY, a citizen of the United States, residing at Norwich, in the county of New London and State ofConnecticut, have invented a new and use ful Improvement in Locks for Fire-Arms, of which the following is a specification.

My invention relates to that class of lirearms, known as double-acting revolvers, in which the hammer may be drawn back to fullcock by the use of the trigger alone, although it cannot be set at full-cock by this means, and in which one spring serves to operate the hammer, the trigger, and the revolver-lever, the object being to simplify the construction and to lessen friction. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a longitudinal view, part in elevation and part in section. Fig. 2 is a detail in elevation showing the moving parts at halfcock. Fig. 3 is detail in elevation showing the moving parts at full-cock. Fig. 4 is a front i elevation of the hammer. Fig. 5 is a front elevation of the revolver-lever.

A A represent the stock, and A2 the triggerguard; B, the revolver-chamber-all ofwhich parts may be made in any ot' the usual. modes.

The hammer C is provided with a half-cock point, o, and a full-cock point, c', and is hung upon a pivot, C. The lower portion ot the hammer C is made with a recess, C2, which di-` vides it into two parts, as shown in Fig. 4. This recess C2 makes a place for the sickle-lever D, the said lever D being pivoted to the hammer C at D. This lever D has a limited motion within the hammer. Attached to the end of the, sickle-lever D by a pivot, D2,is a link, D3, which serves to connect the lever to the spring E. This spring E, acting through the link D3 and lever D, serves to operate the hammer C. It also, throughthe same means, operates the revolver lever or pawl F, and,as the revolverlever F is pivoted at F to the trigger K, it also operates the trigger. The tension of the spring E may be adjusted by the screw E.

To lessen the friction of the end D4 of the lever D in its action on the lever F, I insert a friction-roll at F2, which is connected to the 1ever F by a pin or stud passing through it.

L L' is a pawl-lever or sear for holding the hammer at half-cock, as shown in Fig. 2.

L2 is a spring-piston, which acts upon the Sear L L and throws it into the position shown in Fig. 2, and there holds it nntil the movement of the trigger K, operating atthe point K', throws and holds it out. (See Fig. 3.)

M is a stop,located in a recess made in the stock, and placed immediately under the end of the revolving chamber B, and is provided with a detent, M', which enters the notches P inthe chamber B and holds the said chamber in position, as shown in Fig. 1. This stop M swings and slides on a pivot, N, and is provided with a notch and an inclination at M2. The trigger K has a notch at K2, which engages with the corresponding notch, M2, on the stop M, so that at the beginning of the motionof the trigger K the stop M is drawn downward, as indicated in Fig. 2, and is there held while the hammer` is at half-cock, in which position the stop M allows of the free movement of the chamber B. When the trigger is pulled farther baclr, as shown in Fig. 3, the notches M2 K2 separate, and the stop M iies haclr into position. This latter motion of the stop M is caused by the spring-piston P'. The stop M is pivoted loosely on the pivot N to admit of its being pushed backward by the notch K2 at the return ot' the trigger K, so as to alloT the notch K2 to resume its position of engagement with the notch M2, as shown at Fig. l.

Tohalf-cockmylock thehainmerCis brought back to the position shown in Fig. 2, in which position the revolver may be loaded. To set at full-cock and ready for tiring, the hammer may be drawn back to the position represented in Fig. 3, in which case the notch lo at the Lipper end of the trigger K will hold the hammer by the point c', as shown in Fig. 3, until the trigger is moved, which action will allow the hammer to move forward and explode the charge. At the same time the lever D, acting through its end D4, will throw down the revolver-lever F from the position shown in Fig. 3 to the position shown in Fig. 1.

For occasions when rest at full-cock is not practicable the hammer C may be madeto perform its function by operating the trigger K, the operation being to draw the lower end of IOO the trigger backward, which will cause the upper end to move upward, taking with it the revolver-lever F, and as the point c of the hammer rests on the projection f, attached to the lever F, (see Figsi and 5,) it--the hammeris thrown back about the same as at full-cock, in which position the projection f passes out of engagement with the point c and allows the hammer to fly back and discharge the pistol.

Having thus set forth m'yinvention, what I claim, and desire to secure by Letters Patent, 1S-

1. The combination of the spring E, its connecting-link D3, the sickle-lever D D4, having GEORGE W. GILLEY.
